Description

Technical Field

[0001] The utility model relates to the field of fueling devices, and more specifically, to a fueling device on a screw conveyor mechanism of a cement silo. Background Art

[0002] A conveying mechanism is usually connected to a cement sand tank pipe to facilitate the conveyance of mortar to subsequent processes. The conveying mechanism on a cement mortar tank usually needs to be greased with butter during use to ensure smoother conveyance. The existing fueling devices on the conveying mechanism only set different fueling nozzles, and multiple fueling nozzles are scattered. When greasing with butter, it is necessary to add to multiple fueling nozzles separately, and the fueling process is rather cumbersome.

[0003] After retrieval, the existing patent (publication number: CN204643222U) discloses a fueling device on a screw conveyor mechanism of a cement silo, which includes a cement tank body and a screw conveyor mechanism arranged in cooperation with the cement tank body. The screw conveyor mechanism includes a motor, screw conveyor teeth and a housing. The screw conveyor teeth are arranged in the housing, and the output shaft of the motor is in mating connection with the screw conveyor teeth. The fueling device includes a fueling pipe, a fuel tank, an air compressor and fueling nozzles. The air compressor is connected to the fuel tank through a pipeline. One end of the fueling pipe is connected to the fuel tank, and the other end of the fueling pipe is connected to the fueling nozzles. Adjacent fueling nozzles are communicated through a communicating pipe. By connecting the scattered fueling nozzles with a communicating pipe and changing the traditional way of dispersedly greasing with butter, through the setting of the fuel tank and the air compressor, it is possible to effectively avoid dispersedly greasing at high altitudes. It only needs to add butter to the fuel tank on the ground, thereby increasing the safety of equipment maintenance, reducing labor force and improving work efficiency. The inventor found the following problems in the prior art during the implementation of the present utility model:

[0004] In the existing fueling device, since all fueling nozzles are connected to each other through a communicating pipe, if the oil supply system is not properly designed, it may cause excessive lubrication in some parts while insufficient lubrication in other parts. This will have an uneven impact on the wear between the screw conveyor teeth and the housing, shortening the service life of the equipment. At the same time, when the lubrication requirement changes, the centralized lubrication system may not be able to adjust and respond to specific parts as quickly as an independent lubrication system, thus affecting the operation efficiency and service life of the equipment.

[0005] Therefore, a fueling device on a screw conveyor mechanism of a cement silo is proposed for the above problems. Summary of the Utility Model

Below the cement silo is connected a screw conveyor mechanism, and on one side of the screw conveyor mechanism is connected a motor. On one side of the base is provided a first oil tank, and on one side of the first oil tank is connected an air compressor. On the outer wall of the first oil tank is provided an oil filling pipe, and there are five groups of the oil filling pipes, and the five groups of oil filling pipes are evenly arranged along the outer wall of the first oil tank.

[0022] Embodiment 1

[0023] As shown in the attached Figures 1 to 4 A fueling device on a screw conveyor mechanism of a cement silo, including a base 1 made of metal material, which plays a supporting role. Above the base 1, there is a cement silo 2, which is usually made of high-quality steel, such as carbon steel or stainless steel. These materials can provide good corrosion resistance and strength. For special requirements, alloy materials with higher corrosion resistance can be used. Below the cement silo 2, there is a screw conveyor mechanism 3 connected. The diameter and length of the screw conveyor mechanism 3 should be determined according to the load-bearing capacity and torque requirements. The selection of bearings should consider the shaft alignment and support method, and also the convenience of lubrication and maintenance. A reasonable bearing arrangement can reduce wear and extend the service life of the equipment. On one side of the screw conveyor mechanism 3, there is a motor 4 connected, and the motor 4 supplies energy to the screw conveyor mechanism 3. On one side of the base 1, there is a No. 1 fuel tank 5. The material of the No. 1 fuel tank 5 should be stainless steel with strong corrosion resistance or carbon steel with an anti-corrosion coating. The No. 1 fuel tank 5 should adopt a structural design that is easy to manufacture and maintain, such as a standard cylindrical or cubic shape, and ensure sufficient strength and stiffness to resist possible physical impacts;

[0024] On one side of the first oil tank 5, an air compressor 6 is connected. Since the environment in the cement plant may contain dust and chemical substances, the material of the air compressor 6 should be selected to be corrosion - and wear - resistant, such as stainless steel, special alloy, or carbon steel treated with anti - corrosion, which is usually used to provide compressed air to drive the flow of lubricating oil in the system. An oil filling pipe 7 is provided on the outer wall of the first oil tank 5. The material of the oil filling pipe 7 should have sufficient corrosion resistance, and at the same time, the erosion of cement dust and possible chemical substances should be considered. Commonly used materials include stainless steel, PVC, nylon, or other plastic materials, as well as copper pipes under specific applications;

[0025] The inner diameter of the oil filling pipe 7 is determined according to the required lubricating oil flow rate and the number of lubrication points. The pipe diameter should be large enough to reduce the flow resistance and ensure that the lubricating oil can effectively reach each lubrication point. There are five groups of oil filling pipes 7, and the five groups of oil filling pipes 7 are evenly arranged along the outer wall of the first oil tank 5. One side of the oil filling pipe 7 is connected to an oil filling mechanism 8. There are five groups of oil filling mechanisms 8, and the five groups of oil filling mechanisms 8 are evenly arranged along the horizontal direction of the screw conveyor mechanism 3. The oil filling mechanism 8 is arranged near the lubrication points of the screw conveyor mechanism and is connected to the first oil tank 5 through a series of pipes to achieve accurate measurement and control of the oil volume.

[0026] Embodiment 2

[0027] Based on Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods, such as Figures 1 to 4 as shown, and the details are described below:

[0028] As a preferred implementation manner, the top of the base 1 is obliquely arranged. The screw conveyor mechanism 3 is provided with connecting blocks 9 on the top of the base 1. There are five groups of connecting blocks 9, and the five groups of connecting blocks 9 are evenly arranged along the bottom horizontal direction of the screw conveyor mechanism 3. Further, the oblique arrangement can enable the cement slurry to be transported to the high working surface, saving the handling time. The multi - group evenly arranged connecting blocks 9 can make the screw conveyor mechanism 3 more stable during operation and avoid affecting the overall stability due to the power generated by the transportation.

[0029] As a preferred implementation manner, the position where the connecting block 9 is located is a lubrication point. Each group of oil filling mechanisms 8 is respectively arranged above each group of connecting blocks 9. The bearings of the screw conveyor mechanism 3 are key lubrication points because they bear axial and radial loads. These bearings should be designed with lubricating oil channels to ensure that the lubricating oil can directly reach the inside of the bearings to reduce wear and heat dissipation.

[0030] As a preferred embodiment, the refueling mechanism 8 includes a second fuel tank 10, an oil quantity control unit 11, and a fuel nozzle 12. One side of the second fuel tank 10 is connected to the oil quantity control unit 11, and one side of the oil quantity control unit 11 is connected to the fuel nozzle 12. Further, the second fuel tank 10 serves a specific lubrication point and has a relatively small capacity. The oil quantity control unit 11 can adopt a motor, a pneumatic pump, or a hydraulic pump as the driving method, and select a suitable driving method according to the actual requirements and available resources of the system. The material of the fuel nozzle 12 should have excellent corrosion resistance because corrosive gases and dust often exist in industrial environments such as cement plants. The outlet design should ensure that the lubricating oil can be correctly directed to the lubrication point to avoid oil splashing or leakage.

[0031] As a preferred embodiment, the oil quantity control unit 11 includes a processor 13, a flow sensor 14, and a solenoid valve 15. The flow sensor 14 is arranged on one side of the processor 13. The flow sensor 14 can use the Proline Promass series to provide more accurate flow measurement and can transmit data to the control system. The solenoid valve 15 is arranged on one side of the flow sensor 14. The solenoid valve 15 should have good sealing performance and reliable opening and closing performance to adjust the flow rate of the lubricating oil as needed.

[0032] As a preferred embodiment, the screw conveyor mechanism 3 includes a screw 16 and a housing 17. The screw 16 is arranged inside the housing 17, and the screw 16 rotates clockwise inside the housing 17. Further, the commonly used materials for the screw 16 include stainless steel, carbon steel, as well as various plastics and rubbers. The selected materials should have excellent corrosion resistance. The housing 17 serves to prevent pollutants in the environment from entering and contaminating the internal materials.

[0033] The working process of the present utility model is as follows: First, open the gate of the cement silo 2 to allow cement to enter the screw conveyor mechanism 3. The refueling mechanism 8 is arranged near each lubrication point of the screw conveyor mechanism 3. They are connected to the first fuel tank 5 through a relatively small-diameter fuel pipe 7. Each refueling mechanism 8 is equipped with an independent oil quantity control unit 11. These oil quantity control units 11 will automatically adjust the oil quantity according to data such as the vibration and temperature of the screw 16 conveyor mechanism to ensure balanced and sufficient oil supply to each lubrication point. The above is the working principle of the refueling device on a cement silo screw conveyor mechanism.

[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
